Purchasing Calculator

The Purchasing Calculator computes and compares the price in multiple currencies for two or three commodities measured by weight (mass), volume, area and length.  

Purchasing and Price Comparison Calculators

• Price per Area: Enter an area and cost per unit area to see total cost (e.g., 470 square feet at $3.23/ft²) to see a total cost.
• Price per Volume Enter a length and cost per unit length to see a total cost.
• Price per Weight or Mass:  Enter a weight and cost per unit weight (e.g., 55 pounds at $2.45 per 6 ounces) to see the total cost.
• Price per Ton: Enter the product weight and the price per ton to see the total cost.
• Price per Unit: Enter the total number of units of a products, the unit price per unit number of units (e.g., 500 units at $47 per 20 units).
• Price Compare Two Items by Length :  Enter the length or distance and price of two items, and the calculator tells you which is the better buy and by how much.
• Price compare Three items by Length:  Enter the length or distance of tree items, and the calculator tells you which is the best buy and by how much.
• Price compare Two Items by Area: Enter the area and price of two items, and the calculator tells you which is the better buy and by how much.

Uses for this Calculator

This calculator helps answer questions like the following:

• Which is cheaper? 3.4 pounds for $4.78 (U.S. Dollars), 1.6 kilograms for £5.20 (GBP Pounds Sterling), 420 grams for €2.10 (Euros) or  1.7 kilograms ¥29.32 (Chinese Yuan)?

This calculator makes these and many more calculations trivial by letting you choose your units (length, area, volume, weight and even currency), enter your numbers and get a reliable answer.  NOTE:All currencies whether input costs or output prices have a default of U.S. dollars (USD).  However, the user can automatically convert this via the pull-down menu.
